The device thus described is connected to the frame .6, as indicated in Fig. 4, there being two (a right and left hand), for each end-of the machine, as indicated in Fig. 1,

To the stud 32 of 'the device I' secure a' connecting rod, 47 ',-;l1aving a "slot,"

48, therein, and which rod is connected-at I in engagement with gears 11 and 13; Asjinw gages theratchettoothf and actuates the dicated in Figs. 3 and5, the stud atits farthest distance in relation to the hanger which in gear engaging position i as shown i i i-IZ W m' ee-te oper e dis ngag "t in rn' e e' g :12 t but neeee e y in @1 1 unee eerene fee, which causes thegwheel 27 to rotate, and, as it c rrie t edingr l e l t erensame in 'thedirectionot rotation ,of the wheel, causing the ratchet29 to, rotate aha-1frevolution so that; the, stud 32 will, be 7 urged to the position shown by the dotted lines in Fig; 5, duringwhich movement the connecte ing rod 47 willforce the hanger outwardly and thus disengage the intermediate gear 12 iromgea'rs zllfand 13, wher'eupon'the drive 7 shaftlO-ceases to operate, and the 'fieedruns ondispensersfbeeome idle.
